Windows 7: Device manager: odd behavior

On one of my 2 PCs Device Manager opens with the "Sound, video, and game controllers" list expanded. This is a very minor annoyance, but I'd like to change it if I can. Three sound devices are displayed, and I've got two of them disabled. Does that cause the list to automatically expand?

One of the disabled devices is the onboard sound. I kept it enabled in BIOS so I could rapidly switch from my sound card to the onboard sound if necessary. But I haven't needed to do that for over a year, so maybe it's time to disable it in BIOS.

The other disabled sound device is labeled Intel Display Sound. I think that means it's actually part of my seems to be Intel (onboard) graphics adapter. That's something I have never, and will never use. Maybe there's some way to disable that in BIOS, too.
